When looking for a WordPress hosting plan it can be difficult to judge how much disk space you think you need vs how much you really need. We have found that in many cases, WordPress users severely overestimate the amount, and this, in turn, impacts their purchasing decisions in a negative way. Today we’ll dive into a few ways to better estimate your actual disk space usage needs, ways to find your current usage, and also share some real-world examples that can help you choose the right hosting plan.

How Much Disk Space Do You Need?

Let’s take a quick look at the total disk space vs the number of sites offered on each of the WordPress hosting plans at Kinsta. All of our plans have been allocated resources and limits based on the average disk space usage we see from our own clients (both small and large). This data has been compiled over years from thousands of clients.

Our Hosting Plans

Average WordPress Site Usage

Let’s do some calculations on the actual average usage of a WordPress site. The below data is an average disk space usage taken from a pool of production WordPress sites that have been running for 4+ years.

On average, we’ve found that the typical client has approximately 1 GB of data for a single WordPress installation. Sometimes this can swing in either direction. Some might have a much larger database, but smaller file usage, or the other way around. So on our starter plan, this leaves you with another 9 GB (90%) of unused disk space for growth.

Live Examples

But let’s take a look at some live client examples. The sites listed below are all in production: including blogs, businesses, and ecommerce sites.

Client 1

Client one has 11 WordPress sites and is using 4.04 GB out of their 100 GB disk space allotment. They are well below our Kinsta average, using less than 400 MB per site.

Client 2

Client two has 3 WordPress sites and is using 3.3 GB out of their 20 GB disk space allotment. They are pretty much on par with the Kinsta average of 1 GB per site.

We could keep showing you examples, but this is typical for a majority of the clients at Kinsta. In fact, we even take this a step further and offer these additional ways to save disk space:

Exceptions to the Average

Now, of course, there are always exceptions to the average. For those of you hosting large video files, PDFs, or high-resolution photographs, you could very well easily be at the other end of the spectrum. This is completely normal and we host a lot of clients in this situation. We have two recommendations for users who are low on disk space – our native disk-space add-on or offloading to an external storage provider.

1. Kinsta Disk Space Add-on

The first option is to purchase a disk space add-on in the MyKinsta dashboard. We offer additional disk space, 20GB increments for $20. Choosing our native disk space add-on has its perks.

2. Offloading to an External Storage Provider

The second option is to offload your big files to separate storage services such as Amazon S3, Google Cloud Storage, or streaming solutions.

By offload, we don’t mean using a CDN, although you can combine the following approach with a CDN for the best of both worlds! We mean removing the large files from your origin server (Kinsta) and serving them up from a third-party provider.

Another exception to the average we sometimes see is large WooCommerce sites. However, many of these types of sites deal with a lot of un-cached requests, and therefore clients in this situation are usually already on higher plans with more PHP workers. In other words, these types of sites generally already have bigger plans with plenty of disk space.
